Internal combustion engine



Dec. 8, 1931. E. scHATTANEK INTERNAL COMBUSTION ENGINE Filed June 25. 1928 Patented Dee. 8, 193i ERICE SGHATTANEK, F "VIENA, AUSTRIA INTERNAL COMBUSTION ENGNE Application led June 25, 1928, Serial No. 288,122, and in Austria and Germany June 2Q, 1927.

This invention relates to an internal combustion engine, and particularly to a porous lining for the parts thereof exposed to heat.

The invention is founded essentially on the e perception that a porous body filled with a suitable liquid, for instance, Water, is, even under influence of very high temperature, only slightly heated, if the quantity of liquid evaporated is replaced. The phenomel non on which the invention is based can be explained by the fact that through the influence of high heat, a ihn or coating of steam or gas is instantly formed, which in repose is fairly constant and covers the porous 35 lining, protecting it against further heating. A secondary consequence, is that through the evaporation of the liquid, heat is reduced whereby the Walls of the engine are cooled. As shown, the porous metal lining encloses a@ completely the space in which the heat is operative.

The pressure under which the supply of liquid is effected can be regulated from the pressure Working at the time on the porous i5 metal lining. The duration of supplying the i liquid can also be. regulated during the Working strokes.

The aforementioned effects are made possible by the qualities of the porous metal lining, $0 as to density, Worlrability and shaping, and

also on account of the possibility of a homogeneous connection of the lining. with the Wall to be protected, consisting of metal, which connection can be made by sintering them together, or lby applying the lining in a heated state on the surface to be protected and permitting it to adhere thereto.

The figure represents a vertical sectional view through the device. d0 '-lhe Walls, surfaces and parts exposed the most to heat are provided With a porous lining a. This metal lining a covers the upper ln order to introduce the Water, the pipe 7 is tapped into the cylinder, and leads from a source of Water under pressure.

What I claim is:

1. In an internal combustion engine a porous metal-lining covering the Walls, surfaces and parts exposed to heat, said lining being pervious for a liquid, and means for introducingv the liquid under pressure into the lining. l

2. Internal combustion engine as claimed in claim l, characterized in that the porous metal-lining completely encloses the space Within which the heat is operative.

3. Internal combustion engine as claimed ,m in claim l, characterized by the provision of distributing-channels between the lining and the Wall, surface and parts to be into Whichliquid is introduced.

4. The combination of a cylinder having 5 a power element therein, a porous-metal lining associated With the cylinder and movable element, said lining having channels therein, and means for conducting liquid under pressure into the respective channels.

In Witness whereof I have hereunto signed my name.
